Correlation analyses of kidney variables in AKI demonstrated that urine TIMP-1, NGAL, Uromodulin, and NAG positively correlated with admission urea and creatinine, peak creatinine, and urine protein, whereas the plasma biomarkers NGAL, Cystatin C, VEGF-A and Renin positively correlated with admission creatinine, peak creatinine and proteinuria. This evidence concerns the gene UMOD and acute kidney injury.
